This is a cool plugin, but could seriously use a pair of functions, say deg() and rad(), for converting between degrees and radians. The trig functions assume that the arguments are in radians, whereas most quick calculations with FARR are bound to involve degrees (unless you're a mathie or doing math homework ). So then we could type in "fc sin(rad(90))", for example. Or perhaps the trig functions could be adapted to take degrees instead...

3 - Add an option to change the text that gets on the editbox when you press enter. This is useful for those that don't use the default regular expression (mine is a regex that recognizes mathematical expressions, thus I'd like it to clear the input box on enter press).

While #1 and #3 would just be great to have, i think #2 is a critical fix, as this one annoys me almost every time i use fcalc

regarding #2, you are saying that home+end should go to front and end of the edit line is that right?

it's not just a farr issue, its for any plugin that uses the richtext/memo display mode to display a file or info, so any decision we make applies to all of them. i could use ctrl+home and ctrl+end to go to begining and end of the memo though, and use home and end to go to begining and end of the search box if people prefer.

ps.Fcalc is c++ (C++ Builder) and uses the open source muparser engine to do its math calculations. Anyone feeling adventurous who wants to add some functions and features to muparser, send them to me and i'll rebuild fcalc with them.
